<p>Boundary layer control means to maintain flow of a flowing medium attached to the exterior of a flow control member having a flow control surface, the flow having a flow direction. The means include a channel submerged in the flow control surface. The channel has a first end facing the flow of the flowing medium, a second end positioned downstream in the flow of the flowing medium from the first end, and a bottom surface extending from the first end to the second end. The channel at the first end comprises a first channel zone including a first sub-channel having a first cross-sectional area and a second sub-channel having a second cross-sectional area, the first sub-channel and the second sub-channel crossing each other at a point of crossing.</p> |
